Good evening everyone!
UPDATE…7:30 A.M. EST…FEB 13, 2015: THE FOLLOWING SYSTEM, CURRENTLY IN PROGRESS, IS NOW POISED TO BRING BLIZZARD CONDITIONS TO PORTIONS OF THE EAST COAST FROM NEW ENGLAND NORTHWARD…MAINLY AROUND BOSTON, NORTH.
Arctic air is still on schedule to plunge south, with minimum temperatures that could hit the freezing mark over northern Florida by Valentines Day morning.
Snow and freezing precipitation will once again be in the forecast, beginning over the Great Lakes region early on Saturday, then working east over most of the northern half of the U.S. from VA. to New England, through Sunday morning. The low pressure system responsible for this, will lift northward late Saturday morning / early Sunday afternoon, leaving cold Arctic air in it’s wake.
GFS 48, 54, AND 66 HOUR NCEP FORECAST MAPS
Cold air is currently expected to remain in place over about the southern 2/3 of the country, while temperatures modify briefly over the extreme southeast portion of the U.S. beginning on Tuesday. As this occurs, another area of low pressure is forecast to develop over the AL/GA area bringing moderate to possible heavy rain over the SE on the 17th. I will be revisiting the possibility of probable marginal severe weather around that time given the presence of CCA and WAA being in close proximity. This low is forecast to continue NE, and move offshore of the VACAPES area, becoming the next coastal storm. As this occurs, more snow and wintry precipitation will begin for the portions of the country mentioned previously. Current isobar spacing and wind flags indicate a possibility of blizzard conditions for portions of the NE and New England areas, closer toward the coast from possibly Chesapeake Bay (?), northward. The question mark is there, as this portion of the forecast is 5.5 – 6 days out. This will usher in more Arctic air, with freezing temperatures forecast to be solidly into northern Florida, possibly close to central portions of the peninsula well inland.
Please use the following linked graphics for near real time information updates. Remember to refresh this main page first.
I will try to have one more update, possibly Sunday if I can work it.
I have also gone through my “StormW’s Toolbox” and deleted non working links, and updated outdated links. If you click on the heading, you’ll find a plethora of various weather websites.
Have a blessed day!
